I'd like to modify the line of tasks summary in the Gantt chart. We'd like to display the sub-tasks in the parent task line. We would like to be able to display multiple tasks (children) in a single line (the parent task).

We are using the right-arrow icon as part of the content within a collapsible header to represent a state transition. (See image)

We found that the expand/collapse icon did not appear.

Further investigation reveals that if the header content contains a span with a class matching the regular expression k-i-arrow.* then the expand/collapse icon doesn't work. It could contain anything else, it was just that one class pattern that threw it.

The most important part of using Vue especially in Mobile, is it's small size and performance. Unfortunately, Kendo UI's Vue components are wrappers around jQuery which is something we are trying to avoid in our ongoing developments.
I'd like to suggest building NEW Vue components in full native format with no despondency on other none related frameworks.
Thanks!
